When asked by Autosport if the DTM was continuing to push for a name change, Berger said the series is "working on it", before confirming 2021 as a likely introduction point.

The DTM's bid to become more international has led to comparisons with the short-lived International Touring Car Championship of the 1990s.

A lack of interest and rising costs led to the ITC's demise, and Berger is hesitant to use the joint Class One regulations with SUPER GT to launch a 'world' championship.

"The next step is to stabilise everything in Europe, improve step-by-step. Here [at Brands Hatch] we have more people than last year, great, it's a good step," said Berger. "But it's possible to do another step next year.

"You need to have passion, work hard. In certain countries in Europe, this [Britain] is one of our big names.

"It is important for the manufacturers as it gives the possibility to use the development costs [of Class One] in different continents and that is going to be better.

"It all takes time, you need to pace it. I think everything is moving in a good way."

When prodded further over the comparison with the ITC, Berger added: "You know, with world championships - some are good - but it's connected to high logistic costs, and most of these projects are killed by it.

"If you look at Formula 1 and MotoGP, they have such a big business that the logistics are done in a good way.

"But for us, to do a race in Japan [in November at Fuji], we need to fly a jumbo there and it gets complicated, difficult and expensive.

"I wouldn't run blind in a way [where] we go 'OK, we do a world championship'.
